Face detection/recognition function that will be working in the viewfinder (maybe some type of a hybrid viewfinder? Nikon had several related patents)

Improved video, I have no other details on that but my guess is 1080p/30/25/24 and 720p/60/30/25/24 similar to the Nikon D800

Uncompressed video out through the HDMI port

Ability to assign the two buttons on the front of the camera to smooth aperture control during video recording

Improved 51 AF points

AF detection range will go down to EV-2.0 (the D3s went to EV -1)

Autofocus system: 9 cross-type sensors that are operational up to f/8

Winners over the 1Dx seem to be one more stop of native ISO range (102400) and autofocus to f/8. Fps and resolution are really a wash between the two.

In interesting question in my mind is whether having XQD would give first mover advantage or disadvantage. Firstly, the cards are not on the market, and secondly their reliability and performance is as-ye unknown. - Sounds a bit risky for a flagship product.

The focus points working down to f/8 caught my eye and lead me to believe this is fake. That's one of the few gripes about the 1DX. Seems highly unlikely that Nikon just happens to add 9 of them as Canon eliminates this capability.

When the 1DX dropped, a quote from Canon was something along the lines of "we listened to a lot of pros and what they wanted from a camera", ie, things like the Ethernet port.I wouldn't be surprised if Nikon listened to a lot of the same pros and put their own Ethernet port in, it's waay too soon for them to have just hacked it in since the 1DX was announced.

Uncompressed HDMI is a gift for anyone looking to do video with a DSLR. I suspect that the EOS-C will have this. The D4 needs it because Nikon does not (yet) appear to have any dedicated video products, thus they need to make their existing line more of a hybrid.

Autofocus down to EV-2 and with lenses up to f/8 seems to be the most significant difference for normal shooting.

The 1DX should have XQD in it. Nikon won't have put it in the camera without testing/sample cards from manufacturers, so this is not an unknown quantity for Nikon. XQD will be pinless and faster than CF. What more could you ask for?

I wouldn't be surprised if XQD just wasn't ready for Canon when they were doing the relevant design work for the 1DX.

But I still call this a mashup of 1DX and D3s-improved wishlist...

My understanding was the gigabit ethernet was prettty much becoming a must-have for Canon and Nikon for the Olympics. Both Canon and Nikon need to have cameras with Ethernet in production by then.

Yup, I can believe it. Lots of cameras wired up directly to people's laptops that have empty 500GB drives in them. No messing about with storage cards.

The f/8 autofocus though... I wonder if that'll prompt Canon to get back into AF design and come out with a successor to the 1DX sooner that brings back AF at f/8?

Actually straight to edit suites and news desks. That means that editorial staff will have the shots straight off the camera. I presume that media (press etc.) will be wanting Ethernet from the locations where their shooters are through to the media suites so that reporters and editorial staff have the images immediately. At an event such as the Olympics, you will have a complete stadium LAN infrastructure, so you are not limited by the length of a CAT5/CAT6 trunk+flylead. I presume each media organisation will get its own VLAN. If VLAN membership is by MAC address, that means that, for instance, if I am a Reuters shooter, and the MAC address of my camera is recorded as being part of the Reuters VLAN, that means that I can just plug in anywhere there is a LAN point and have my photos immediately going back to my editorial suite.

Cisco will be making some big bucks out of the network infrastructure for the London Olympics!
